Time: 13:00 Room: S5

Abstract

In this talk, we will delve into RAUC, the embedded Linux update framework, focusing on its unique features and advantages for managing system updates.
The presentation will begin with an introduction to the fundamental concepts surrounding A/B fallback and update signing in the context of embedded Linux updates. We will then explore how RAUC addresses these concerns by offering a flexible building block for streamlined update management.
The discussion will progress to cover RAUC's bundle-based update system, which allows for comprehensive system updates without the need for local storage, thanks to HTTP streaming. Additionally, we will demonstrate how adaptive updates minimize download sizes without necessitating version-specific patch management.
